Its results have come a long way from the research process and have found practical aspects. Meanwhile, carbon nanotubes and golde nanoparticles have a clear effect. Carbon nanotubes and gold nanoparticles are capable of chemical and biological compatibility with different cells base on their unique properties iIncluding shape, conduction, surface properties and electrophoresis and this has made them very attractive in diagnosing and treating of cancerous tissues. In laser treatment method, carbon nanotubes absorb light at wavelengths due to two volatile directions While gold nanoparticles often fluctuating in one direction, absorb light at shorter wavelengths. Hence, carbon nanotubes are suitable for the treatment of cancerous tumors that are located in the deep parts of the body and gold nanoparticles are useful for the treatment of surface tumors, such as skin cancer. There are many methods for the synthesis of carbon nanotubes and gold nanoparticles. But the chemical vapor deposition method for carbon nanotubes and the Faraday method for gold nanoparticles is the most appropriate method for use in medicine. Gold nanosheets are used as sensors for the detection of cancer cells and can be used to the detection of cancer cells without any side Injury. Also, single-wall carbon nanotubes are used as precision nanosensors in the diagnosis of cancer cells. They can produce a wire sensor by attaching a special antibody.
